Toldi tanks entered Hungarian service in 1940. They first saw action with the Hungarian Army againstYugoslavia in 1941.

These tanks were mostly used against the USSR between 1941 and 1944. Because of their light armour, armament and good communications equipment, they were mostly used for reconnaissance. The design was not effective in head-on engagements with Soviet T-34 medium tanks encountered during the early stages of Operation Barbarossa.
